Windows 10 upgrade problems/Inspiron 14R 5437

Hi....I recently got a "new" open box Inspiron 14R 5437. After getting it all up to date, I decided to go with the 10 upgrade. The upgrade procedure went well,.....but I have multiple issues with the task bar area....no start menu, no Cortana or search,.....nothing works as expected in the clock/date area,.....some of the other taskbar icons will respond to right click,...but left click to open does nothing.....

I decided to roll back to 8.0,......then went to 8.1,........tried 10 again,..still issues as before.
